MKDIR %destination%\%foldername%

FOR /F "tokens=1,2 delims=," %%i IN (backuplist.txt) DO (

    SET completeSource=%%i
    SET completeDestination=%destination%\%foldername%\%%j

    ECHO Source: "!completeSource:"=!"
    ECHO Destination:"!completeDestination:"=!"

    MKDIR "!completeDestination:"=!"
    XCOPY "!completeSource:"=!" "!completeDestination:"=!" /E /F
)

REM Zip the folder using the 7z command line utility
%sevenZip% a -tzip %destination%\%foldername%.zip %destination%\%foldername%

REM Remove the unzipped backup folder
RMDIR /Q /S %destination%\%foldername%

PAUSE

这是我过去几天一直在使用的备份批处理文件。直到今天早上它都运行良好。出于某种原因，当它创建变量foldername 时，它在字符串中包含一个以前没有的空格。结果是这样的：

svetlana_backup_22092016_ 93829

由于某种原因，破折号和 93829 之间的空间直到今天才出现。我将如何删除它并防止它再次发生？

Answer 1

您可以像这样解析文件/文件夹名
set foldername=%foldername: =%

这会将所有空格替换为空字符串

问题可能是因为测试是在小时仅包含一位数字时运行的。 %Time:~0,8% 将输出包含额外空格的时间，因为时间将像这样存储：9:38:29 是 7 个字符，您读取最后 8 个字符。
